Why are courts often reluctant to decide internal religious disputes?

Courts in the United States are generally cautious about intervening in the internal affairs of religious organizations, particularly where a dispute would require the court to decide questions of religious doctrine, governance, or the selection of religious leaders. This principle — sometimes described as ecclesiastical abstention — means that a congregation cannot always count on a court to resolve an internal conflict, and even when a court can hear a related civil or property question, it may decline to reach the underlying religious issues. This makes mediation particularly important for faith communities: it offers a forum to resolve disputes that the civil courts may be unable or unwilling to decide, and it lets the community resolve them according to its own values.
